Hello, I recently installed RHEL 4 on 2 systems with the default samba packages : samba-common-3.0.10-1.4E samba-swat-3.0.10-1.4E samba-3.0.10-1.4E samba-client-3.0.10-1.4E Now I have successfully linked this server to our Windows domain. This means that all the windows IDs are known. Now we have our systems setup so that the windows accounts are linked to existing Linux accounts with the smbusers file. In effect the windows user become there linux counterpart user when accessing his/her home from windows( e.g explorer ). This means all files created in windows in there homes, have the linux user permissions and ownership. This setup is configured and working on several other server RHEL3 and HP-UX11.11 servers. But on the RHEL4 the link to the existing Unix account seems to be broken? The users are known, "# id Windows.Account ", will show me there account. But when they connect with windows( e.g explorer ) they remain in there windows account and this shouldn't happen. Because of the smbuser file they should be linked to there existing Linux account, and all the files they create should contain there linux account permissions and ownership. But this is not happening! They remain in there windows account, and files generated are with this accounts ownership and permissions. Also the GNU&Linux accounts have been setup by a NIS, in case this would be important. contents of the smb.conf, basic setup actually : [global] workgroup = <Removed> realm = <Removed> server string = Samba server security = DOMAIN auth methods = winbind obey pam restrictions = Yes password server = <Removed> username map = /etc/opt/samba/smbusers log level = 3 log file = /var/log/samba/smbd.log max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = No ldap ssl = no idmap uid = 10000-20000 idmap gid = 10000-20000 template shell = /bin/bash winbind separator = / winbind cache time = 10 winbind use default domain = Yes hosts allow = 192.168.1. [homes] comment = Home Directories path = %H read only = No [sharing] comment = File sharing area path = /home/sharing read only = No guest ok = Yes and the layout of the smbusers file is: LinuxAccount = DOMAIN\Windows.Account etc... also tried layout like this LinuxAccount = Windows.Account etc.. but no effect. Does anybody have any more ideas of what could be wrong? -- Kristof.Bruyninckx We are Microsoft. What you are experiencing is not a problem; it is an undocumented feature.
